Why wouldn’t they? According to Öhlins... “Compared to the old gas pressurized system, the spring pressure offers a more simplistic and user friendly design. That also accounts for easier maintenance and setting changes. But there are more advantages of a spring pressurized system. There is no risk of gas leakage, it also gives a more consistent performance curve and allows for a more compact design.” Guess this was more of a tech question. I sincerely would like to understand.
Oh wait, so the old forks had NO springs in them at all, only gas pressurized? Were they basically like the "air forks" that were briefly employed in motocross and then shit-canned? I thought the old forks had both a spring inside them AND they were gas pressurized?
One of my friends built this. Problem is, the engine won't fit. Even with removal of the airbox the shower head injection hits the frame crossmembers near the steering head. But of course, Ducati could figure it out. My buddy had to do some serious backyard engineering to his.
I have a 1198 engine in a 996 frame. It's a pretty easy swap by flipping the linkage to clear the frame brace and a custom airbox I am also finishing a 1198 engine in a 999r frame with full 62.5mm Corse exhaust
So what are we splitting hairs over then? They both have springs, they both are gas pressurized and they both have compression in one leg and rebound in the other. The new ones simply don't use and external pressurized tank at the bottom of the fork leg?
No, I'm not a big fan of single arms on non-single bikes. I am looking for an underslung brake caliper bracket so the BREMBO is not upside down.
The gas canisters that pressurized the oil are now spring canisters. But I don't know why he's getting worked about about Ohlins waffling over spring vs gas for the oil pressurization.
Sweet 999! Have you looked at Durbahn for inspiration? Although his is a hidden setup. http://durbahn.de/Durbahn-Shop/shop.durbahn.de/shop/de/products/Bremse_hinten_superleicht.html I sure it wouldn't be too much of an ask to model one up 180 out if you were willing ($$$) to have something bespoke.
Haha. Not worked up, just a bit surprised Ducati and now Yamaha didn't use the FKR. I guess is must be cheaper to produce this completely new fork for some reason.
If I had to guess, the spring canisters are heavier but they won't require as much maintenance as the gas will. And since they're OEM on a street legal bike, the weight savings don't outweigh the increased servicing needed.
So sweet! I prefer the DSS on the 999R as well, easier to maintain settings when changing gearing, plus it just looks good on those bikes. That's my favorite Ducati chassis too. A lot of the good stuff is getting harder to find. Moto Corse used to offer an underslung caliper kit for race 64mm caliper spacing.
Air forks are alive and well in the MX world, at least for KTM and Husqvarna makes in the AER48. It’s a really sensitive fork, and being able to adjust how the front works when an air pump in a few seconds is nice.
The pressurization they're talking about isn't to hold the suspension up. Both are to pressurize the gas volume above the fork oil to prevent cavitation. That can be done with a gas chamber (like a rear shock) or it can be done with another spring and a piston.
It's based on the Corse bracket I think. They copied the one from my 749RS. I am pretty sure I know the machinist that made it, but it was not cheap as I recall.
I was talking about Moto Corse in Japan/Italy not the guys in Florida. It was actually a kit with the full floating rotor too. Discacciati is the only caliper bracket (84mm) I've seen recently, don't know if you can buy it without their caliper or not.
